Lead-germanate glasses and fibers: A practical alternative to tellurite for nonlinear fiber applications
(2013-09-20)
We report on the fabrication of novel lead-germanate glasses and fibers. We have characterized these glasses in terms of their thermal properties, Raman spectra and refractive indices (both linear and nonlinear) and present ...

Finite element analysis of anisotropic optical waveguide with arbitrary index profile
(1999-12-01)
This work presents the application of a scalar finite element formulation for Ex (TE-like) modes in anisotropic planar and channel waveguides with diagonal permittivity tensor, diffused in both transversal directions. This ...

Method for real-time measurement of the nonlinear refractive index
(American Institute of Physics, 2019-09)
In this work, we propose a novel method for continuous real-time measurement of the dynamics of the nonlinear refractive index n2. This is particularly important for characterizing phenomena or materials (such as biological ...
Relation among optical, thermal and thermo-optical properties and niobium concentration in tellurite glasses
(Elsevier B.V., 2010-09-01)
In this work, optical, thermal, thermo-optical and spectroscopic properties of the 80TeO(2)-(20-x)Li(2)O-xNb(2)O(5) (x=5, 10 and 15 mol%) glasses were investigated by using the thermal lens spectrometry, X-Ray diffraction, ...

Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
(2007-12-01)
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...
